bgpd: Check L3VNI status before announcing default

Browse source 
Check that the L3VNI is "up" before taking action to announce or
withdraw the EVPN type-5 default based on configuration. Otherwise,
there can be timing conditions where a EVPN type-5 default route
gets announced without a VNI and with invalid route targets.
